subtle is a grid-based manual tiling window manager with a strong focus on easy but customizable look and feel. In comparison to other tiling window managers, subtle has no automatic tiling of the screen size in any way. Instead, windows are arranged according to positions inside of a grid. These positions are called gravities.

Jumper provides an enterprise bookmarking engine for tagging and linking data objects. It lets you search and share high-value data across remote locations using tag metadata (expanded tag fields) to capture knowledge about data in remote data stores. It collects these tag profiles in a knowledge base where user-created tag profiles identify quality data
resources, user-contributed tag information adds
real-world knowledge about the data resources, and
user-created reviews sort out the worthy resources
from the inadequate. Other users can search for this data. In addition, they can directly contribute what they know about this data to the knowledge base. It allows the participants to act as a filter for what is
valuable and build upon mainstream pursuits, but
also uncovers valuable data hidden at the edge.

MP3 Diags finds problems in MP3 files and helps the user fix many of them. It looks at both the audio part (VBR info, quality, normalization) and the tags containing track information (ID3). It has a tag editor, which can download album information (including cover art) from MusicBrainz and Discogs, as well as paste data from the clipboard. Track information can also be extracted from a file's name. Another component is the file renamer, which can rename files based on the fields in their ID3V2 tag (artist, track number, album, genre, etc.).

tagls is a tool that matches file names using boolean expressions made of tags and regular expressions. It handles searching in file lists with word boundaries for "tags", stemming and synonym expansion for both tags and regular expressions, and boolean expressions over lists of tags or regular expressions. It can match against either the file name or the file's content. The output can be unsorted, sorted by name, or sorted by relevance.

puddletag is a tag editor for Linux loosely based on mp3tag. It uses a table layout so that all the tags you want to edit by hand are visible and easily editable. puddletag excels at automating repetitive tasks like extracting tag information from filenames, tagging files from a text file or the clipboard, renaming or moving files and folders based on tags by using patterns, and manipulating tags using actions and regular expressions. Supported formats include id3v1, id3v2 (.mp3), AAC (.m4a), VorbisComments (.ogg, .flac), and APEv2 (.ape). Much of mp3tag's functionality has been replicated with added enhancements and tweaks.

The AlchemyAPI Android SDK enables real-time semantic analysis of text, HTML, or Internet-hosted Web page content. The SDK provides mechanisms to extract Concepts, Named Entities, Keywords and Tags, Categories, and clean HTML into text, and even detects languages. It can analyze text in eight different languages: English, French, German, Italian, Portuguese, Russian, Spanish, and Swedish. Example code and a demo application are included to help get you started.

PhotoCatalog can import GPS data from various formats such as CSV, GPX, and InstaMapper (in the case of InstaMapper, it is a live stream) and create a Map that is updated live during your travels. It can also import data from Twitter or FourSquare, RSS extract any GPS data they have or supplement them with existing GPS data, and place them on a map as well as keeping a personal archive. It can then import photos via file upload, email, or scanning an existing folder, geotag photos lacking GPS data, sort, rotate, scale, and [losslessly] compress them as necessary and place them on a map. It can also push them to Facebook automatically and fill in a caption and/or comment with them.
